Your First Project

Once your system is setup, you can start to create new projects or open existing
Arduino projects created in the classic Arduino IDE.

If you are familiar with the classic Arduino IDE, you know the concept of
sketches. Arduino Sketches are software projects consisting of one or more
source files, which have the file name extension .INO in the classic
Arduino IDE (.PDE in early versions of the Arduino IDE). Sketches are organized in folders on your disk.

In Atmel Studio and Visual Studio these are called projects,
which also consist of several files that together build a complete software
program. Visual Micro makes it easy to create projects
from scratch or to convert existing Arduino sketches into projects.
